Why Lesson Planet?
Who hasn't enjoyed snapping rubber bands at some point in their lives? Here is a chance for your young chemists to snap them in class! In order to determine the effect of temperature on elastomer materials, science learners experiment with rubber bands and polyethylene. They hang weights from each and measure the difference in length after applying the heat of a blow dryer. Procedures, a sample data table, and background information are provided to make your teaching experience a breeze.
